general problems of the 2022 GMC Yukon - part 2

While driving in the left lane of the interstate at 70 mph, the engine abruptly shut off, shifting the car into neutral. The dashboard read start engine, which did not compute immediately. I quickly navigated to the right lane to assess the situation and eventually to the shoulder of the highway where I parked the vehicle. I was unable to to restart and had the vehicle towed to the dealership. It took ~6 hours for the onstar tow service to arrive.

While driving the transmission will slip/hard shift very aggressively causing the rear tires to lock up. This would happen at unpredictable speeds (anywhere between 10mph-65mph), this occurred for about 2 weeks before vehicle ever gave a code. Very scary and dangerous especially if you are in traffic since it essentially "brake checks" those behind you. The last incident that finally provided a code occurred at 50 mph when the rear tires completely locked forcing the vehicle in park. Could no longer drive the vehicle after this. The error code states that a rear body valve is needed for the transmission which the dealer is unable to get and neither the dealer or manufacturer can provide any estimate of arrival. Has been in the shop for almost 2 months now waiting.

At highway speed, in heavy traffic, and falling snow, the engine seized with sudden loss of power, including loss of brake and steering sensitivity. We were traveling downhill so, while avoiding other traffic and weather, maintained momentum to pull over to the side. We were stranded at night in snowy weather in remote utah. It took hours to get towed to the nearest town, fillmore, where the mechanic determined that the engine was seized and that no mechanic in the town could repair the issue. Gm would not tow vehicle to our home, they would only tow to nearest dealership - which was farther away from our home (over 3 hours away). After repeated attempts with gm for tow assistance over the course of 13 days, we towed the vehicle to salt lake city, our home city at our own expense. The dealer said 6 of 8 rod bushings were bad, ordered a new engine which took over 2 months to receive and install. Catastrophic event occurred [xxx], time trying to get gm to tow vehicle, ending with our own expense 2/26/2025, finally returned from dealership with new engine 5/1/2025 - 64 days from dealership receipt of vehicle - 77 days from catastrophic event. Continues to have electrical issues that affect controls like radio, ac/heat, start/stop. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Valve body needs replaced, been waiting over 10 weeks for replacement. Vehicle only has 28k miles and wouldn’t reverse or shift past 2nd gear.

My vehicle radiator fan immediately cut on high when I turned on the vehicle. The temperature of the vehicle was normal. I also experienced this when the engine was completely cold. I was assured there was no need to tow the vehicle but I could drive and schedule service with dealer. The software triggered a reduced acceleration condition. This did not allow me to accelerate as needed while navigating an interstate interchange.

1-'engine oil low add oil' warning sign is being displayed. Vehicle is burning oil with no leakages. Warning sign has come on multiple times; authorized manufacture dealer service center finds no failure. Independent service center finds oil consumption to exist without leaks anywhere and beliefs this is due to a known engine failure in this model. 2-'service transmission now unable to shift soon' warning sign appears while driving but authorized manufacture dealer service center is unable to reproduce or determine issue.

Sudden loss of power while driving approximately 60 mph. Dash saying "press engine start". The vehicle lost all functions while moving at about 60 mph with zero warning signs. After diagnosis with the GMC dealer, crank bearing failure led to complete motor loss. The concern was there was no warning signs, noises etc. That would allow to get the vehicle to a safe location off the road. We were lucky we were going straight and not on a corner and able to coast to a wide enough location to get the vehicle off the main lanes of traffic.

We were driving south on [xxx] when lights on the dash started flickering and the vehicle switched itself to neutral and had a sudden loss of power. We were lucky enough to get out of traffic and spent 5 hours waiting on roadside assistance and a tow truck. It was a very dangerous situation. The service department at sullivan GMC ocala (352)-414-4962 first said that replacing the fuel module would fix it. 5 days later they said it needs a new engine. They plan to replace it with the same 6. 2 engine. (same part number that is defective) the electrical safety system should be recalled. With no warning, the vehicle loses power and stops. GMC and every service department manager that I have spoke to knows about this issue. GMC continues to market and sell these engines and vehicles. Someone is going to get seriously hurt or killed because of GMC's negligence. GMC case [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was driving on an expressway in chicago heading to work at 5am on [xxx] morning. While driving my engine shutdown and I lost engine power to my vehicle while doing 70mph. There was no warning, no warning lamps and no noise to indicate there was any issues. The vehicle just died while I was driving. I had to coast to the shoulder with traffic all around me. Luckily I was able to avoid other vehicles and they were able to avoid me when they realized I was having trouble. Though there was a very close call where I almost got into an accident. When I pulled onto the shoulder the vehicle completely shutdown. It would not restart. I had to call a tow company to have my vehicle towed to the dealership. Luckily, I was able to find one nearby that was open at that time on christmas eve. The dealership mechanics went over my vehicle and determined that I had complete engine failure. The bearings on the bottom end of the engine spun out. I now need a complete engine replacement along with whatever other components were also damage. This incident was a major safety issue. I was luckily that I did not end up in a major accident due to the loss of complete engine power. This is a major issue that needs to be looked into and gm needs to be held responsible for not only my vehicle but all others that this is happening to.

The engine started making a rattling sound. Brought it to the dealer and they told me the engine is bad and it needs a new one. They told me this issue with lifters and the fuel management system is a common problem leading to internal metal components breaking. My car has been with the dealer since 12/30/24 and I was told this week from the dealer the problem is so big there aren’t any engines available and they have no idea when I’m getting it back. When I initially dropped it off, they said approximately a month. Now they are saying they don’t have a clue.

Engine failure as a result of a bearing failure. I have been waiting since December 3, 2024 for a replacement engine.

My transmission began having problems the day it was delivered to me. After the oil change which they delivered to me at low percentage was completed the motor was ticking. It has had a burning smell and has been in and out of the shop and going back soon. I was on the expressway and the speed declined with error messages on the dash almost resulting in an accident. No one is listening to my concerns and now the motor has a metal clinking noise.

I bought my 2022 Yukon xl on [xxx]. On Friday [xxx], only a few weeks after having my car in the shop (at the dealer) for running rough, it started to make an odd high-pitched noise and running very rough at higher speeds. I immediately called the dealer and asked how quickly I could bring the car in to be checked. They said they had no availability for over 10 days, and offered me an appointment for then. By the next morning, it seemed to be running better and I didn't have to drive much that day so I hoped it would make it until the appointment. That Sunday [xxx], my husband and I drove the car to a sporting event with our children and it seemed to be ok. On our way home, however, just after crossing a long causeway over the bay, the car's motor just stopped working in the middle of driving on [xxx] in miami. We were in the left lane and had to try to change multiple lanes while coasting only, and were only able to get off the traffic lanes because there happened to be a side street that came up quickly enough to turn onto before the car came to a stop. It was completely unexpected and without warning, and had we been on the interstate or even the causeway we had just come off of, it could've easily caused an accident with my whole family in the car. Once stopped, it wouldn't crank or even try to turn over, no matter what we tried. It took 2 tow trucks because we couldn't even change/move gears enough to put it in neutral, so couldn't use the flat bed that arrived first. We were stuck for hours in a less than desirable area of town. The dealer took a week to look the car over, then said the engine had seized up and would need to be replaced. The engine was on back order and it took over 6 weeks for the replacement. After replacement, 2 separate issues arose over the following 2 weeks, each the result of a component not being properly tightened during the engine replacement by dealer service technicians.

My wife and I were going 70 plus mph on [xxx] in georgia in the far left lane. Our car completely lost power were had to maneuver across 2 lanes to get to the emergency lane it was very scary traffic was blowing horns and it was awful. We made it to the emergency lane and proceeded north at a creeping pace with engine making lots of noise. We made it to a hotel next to [xxx] we were in savannah georgia. We tried to contact the local GMC dealer but it was after hours so we stayed the night and next morning got a tow to critz GMC. At critz we were informed our engine was beyond repair and needed replacement. They proceeded to offer me $10,000 on a trade in, said it would take 3 months to get a replacement engine so I called my dealer back home white motors roanoke rapids nc and they advised it would take several months to get a new eng and they couldn't tow me in so I called david towing and they said they would come get it for me in the next week. We to enterprise to rent a car and there were none available for a week I decided to buy a new car from critz to get home .

With no warning ,the GMC 6. 2l engine failed on my family trip to colorado. The engine seized at hwy speeds, stopped running, failed to restart and had to be towed to local dealer. This issue is a known GMC defect with numerous reports and a safety recall issue. I was fortunate to be able to move offer in hwy traffic and get to the shoulder where my situation took 8 hours travel time to continue my family trip.

Transmission shifting gears sporadically between 49-57 mph and 19-24mph. If I’m driving at 53 mph, I take my foot off the gas and slow down to 50 mph, when I start to slowly accelerate again, it jerks and makes a loud noise as if the transmission has trouble shifting. Took it to the dealer 3 times now. First time they said they can’t find anything wrong. Second time they replaced a valve body that supposedly would fix it. It didn’t. Third time they couldn’t find anything wrong with it. I don’t feel safe driving around my 3 kids all the time.
